Detailed ways

In order to make the above purpose, features and advantages of the present utility model more obvious and understandable, the specific implementation of the present utility model will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a full understanding of the present invention. However, the utility model can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below limit.

It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of this invention. The terminology used herein in the description of the utility model is only for the purpose of describing specific implementations, and is not intended to limit the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in Figures 1 to 2, a crystal head limit structure for a switch includes a switch body 1, a number of crystal joints 2 are detachably inserted at the signal interface of the switch body 1, and the lower end of the switch body 1 is hinged limitedly. Position card slot 3, the limit card slot 3 includes a fixed ear 31 and a slot body 32, the fixed ear 31 is arranged on both sides of the slot body 32, and the fixed ear 31 is connected to the switch body 1 through a pin shaft, the slot The body 32 is provided with several notches corresponding to the wiring harness of the crystal connector 2 , and elastic pieces 321 are installed on the inner side walls of the notches for clamping the wiring harness of the crystal connector 2 . Specifically, in this embodiment, the switch body 1 is a network switch, which is an office network distribution switchboard or an extension. The switch body 1 is a metal shell with fast heat dissipation. Several electronic components are arranged in it for signal interaction. The switch body 1 The signal interface at the rear end is installed on the mainboard of electronic components, and leaks out for plugging into the crystal connector 2 . The connection between the existing switch body 1 and the crystal connector 2 is in-line. When the crystal connector 2 is inserted into the signal interface, the wire harness at the end of the crystal connector 2 is directly scattered outside. Touching the wire harness may cause the crystal connector 2 to be disconnected. The interface with the signal is skewed, causing communication failure. In this design, there is a limit card slot 3 at the rear end of the switch body 1 through a pin shaft or a hinge. The limit card slot 3 can rotate around the connection with the switch body 1. When the crystal joint 2 is connected normally, the rotation limit The slot 3 makes the notch "bite" the wire harness at the end of the crystal connector 2, and clamps it with the shrapnel 321 to prevent the user from touching the wire harness by mistake in the office, causing the crystal connector 2 to loosen and causing computer network signal failure. When it is necessary to unplug the crystal connector 2, it is necessary to rotate the limit card slot 3 first, so that the groove body 32 is separated from the wire harness of the crystal connector 2, and only then can the crystal connector 2 be inserted and inserted normally, preventing users from accidentally plugging and unplugging the crystal connector 2. Improve the safety redundancy when the switch body 1 is in use.

As shown in FIGS. 1-2 , heat dissipation fins 11 are installed on the upper end of the switch body 1 , and heat dissipation holes 12 are provided on both sides of the switch body 1 . Specifically, the heat dissipation fins 11 can increase the surface heat dissipation area of the switch body 1 , and the heat dissipation holes 12 serve as air passages communicating with the outside world to dissipate the heat inside the switch body 1 .

As shown in FIG. 2 , a fan 13 is installed facing the inner side of the heat dissipation hole 12 , and the fan 13 is separated from the heat dissipation hole 12 by a dust-proof net. Specifically, in order to further improve the heat dissipation effect, the fan 13 is used as air cooling to dissipate the heat generated by the components working in the switch body 1, and at the same time, in order to prevent external dust from entering the switch body 1 from the cooling holes 12, Use a dust filter to isolate dust.

As shown in FIG. 1 , foot pads 14 are provided at the four corners of the lower end of the switch body 1 to prevent the switch body 1 from being placed on the ground directly. During displacement, the metal surface at the lower end of the switch body 1 is easily scratched.

As shown in FIG. 1 , the foot pad 14 includes a sleeve 141 and a rubber stud 142 , the sleeve 141 is integrally connected with the switch body 1 , and the upper end of the rubber stud 142 is screw-mounted in the sleeve 141 . Specifically, by screwing the rubber studs 142, the length of the rubber studs 142 at the four corners of the switch body 1 protruding from the sleeve 141 can be adjusted, and the switch body 1 can be placed horizontally on uneven ground. Moreover, the main body material of the rubber stud 142 is relatively soft, which acts as a shock absorber.

The above-mentioned embodiments only express several implementation modes of the utility model, and the description thereof is relatively specific and detailed, but it should not be understood as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
